It would be nice to have a central bus terminal in Jewel Changi
Airport, instead of 3 separate bus terminals in T3, T1 and T2.

Ideally, a central bus terminal should
- save travelling time by avoiding 3 security checks (as the buses
would stop outside the terminals, not under the terminals)
- allow double deckers (Services like 27, 53 and 858 deserve double
deckers)
- allow BCs to take breaks
- allow longer routes from the airport as the routes no longer need
to loop at the airport
- allow quick transfers between buses, MRT, skytrain, and T4
shuttle

I don't think you are giving enough justice to the role of 48 in
this sector.

48 serves as a supplement to these services. You better believe
it when I say this, as both 2 and 9 can be heavily delayed by jams
in Bedok, and this is where 48 steps in. If you realise carefully
48 almost always arrives at independent intervals from 2 and 9, so
it does not bunch with the two. Deliberate or not, it shows how
important 48 is for Simpang Bedok, esp during weekends when many
ppl go there.

I'm puzzled by your choice of substitutes in the other sectors
you mentioned, as none of them can be direct competitors against
48, they serve completely different groups. 25 is used for people
who want to go to Bedok specifically, not those travelling on the
MRT, where 48 would've brought them to TNM in much shorter time.
14's intended travellers aren't even those staying along UEC,
rather most of its pax alight at Bedok Rd.

And to those wondering what will happen to 48, nothing will!
Read the post carefully, it says no NEW svcs ley.

Alternatively, extend svc 17A to UEC terminal via 48's route
from Bedok North Ave 4 to Bedok South Ave 3, and give svc 17A a new
number. After that, you can do whatever you want to svc 48 (be it
extended to CBP or shortened to UEC).

Ever since 17 and 17A were transferred to Go Ahead, 17A has to
make a big loop after BNDEP as it cannot use SBST-controlled BNDEP
to "U-turn". 17A may as well be extended to provide more options
for residents along Bedok North Ave 4 and Bedok North Rd.

Haha you list all these whatever reasons also no use.. anyway
all these reasons I mentioned before..

becoz CAAS and LTA made it v clear.. NO CENTRALISED TERMINAL for
CGA svcs, becoz us peasants are undeserving of such..

Jewel ah, you wish haha.. I alr emailed CAAS, they confirmed no
terminal inside Jewel.. And no infra is in place for any future
devt for it..

I would gladly trade 17 for 29.SBST can renumbered 17A as 164
and terminate at UEC.48 can extend to CBP.

A similar route variant operated before between 1994 and 1995,
until 165 was extended to Hougang Central in 1995. So I don't know
if it's ironic that it is reintroduced to "supplement 165" when 165
was extended to replace it.
